Talking to friends about really good PS1 games, and I remember GC. I was talking to them about it, and remembered the toys. Now...I can't remember, but I believed there to be 4 'Legendary' toys that, if you had collected them before the end boss(can't remember his name, sorry), they would significantly help you? Is this true, or am I just making this up? =S

I'm afraid that you are possibly mistaking these four "Legendary Toys" as the four Legendary Pieces of Holy Armor, which you must collect to complete the game.

However, I suppose you can say that there are two "Legendary" toys. One of them is the Living Toy called Legend, who costs 50PP to summon, but always deals 600+ damage per turn. The other one is called Peacemaker, and for the price of all of your PP, he will knock Knight down to 1HP (if his HP is full), kill Baby, and kill all the enemies in the fight. Legend could be considered legendary because he can only be acquired when you have all 68 of the other living toys (scratch Peacemaker), and he's insanely strong. Peacemaker could be considered a legendary because he can only be acquired after obtaining Legend; you can't receive him before you have Legend. You do not have to have Peacemaker to receive Legend because Dr. Zeppetto, the creator of the living toys, considered Peacemaker to be too dangerous of a creation for the world, so he threw him into the ocean from his island.
